10 Toxic Ingredients to Watch Out for in Your Dog's Food

9. Carrageenan: A Thickening Agent with Potential Risks

Carrageenan is a common thickening agent derived from red seaweed, used in both human and pet foods to improve texture. While it is considered safe by some regulatory agencies, research has raised concerns about its potential to cause inflammation and gastrointestinal issues. Carrageenan has been linked to digestive disturbances in some dogs, leading to symptoms like diarrhea and vomiting. The controversy surrounding carrageenan stems from its degraded form, poligeenan, which has been associated with cancer and other health problems. Although food-grade carrageenan is different, the potential for degradation during processing raises questions about its safety in pet food. To err on the side of caution, consider choosing dog foods that do not contain carrageenan, particularly if your dog has a sensitive stomach or a history of digestive issues.
